Ps 110:10

“It has also been a subject of discussion, how extremely frequent is the intercourse that heretics hold with magicians, with charlatans, with astrologers, with philosophers; and the reason is that they are people who devote themselves to curious questions. "Seek, and you shall find," is everywhere in their minds. Thus, from the very nature of their conduct may be estimated the quality of their faith. In their discipline we have an index of their doctrine. They say that God is not to be feared; therefore all things are in their view free and unchecked. Where, however, is God not feared, except where he is not, there truth also is not. Where there is no truth, then, naturally enough, there is also such a discipline as the heretics. But where God is, there exists "the fear of God, which is the beginning of wisdom." Where the fear of God is, there is seriousness, an honorable and yet thoughtful diligence, as well as an anxious carefulness and a well-considered admission [to the sacred ministry], a safely guarded communion, promotion after good service, a scrupulous submission [to authority], a devout attendance, a modest gait, a united church and God in all things.”

“Fairer in my eyes is the beauty that we can gaze on than that which is painted in words; of more value the wealth that our hands can hold, than that which is imagined in our dreams; and more real the wisdom of which we are convinced by deeds, than that which is set forth in splendid language. For "a good understanding," he said, "have all they who act accordingly," not they who proclaim it. Time is the best touchstone of this wisdom, and "the gray head is a crown of glory."”

“I think I shall not seem to be taking too much on myself, if, in the midst of my children, I yield to my desire to teach, seeing that the master of humility himself has said, "Come, you children, listen to me: I will teach you the fear of the Lord." Therein one may observe both the humility and the grace of his reverence for God. For in saying "the fear of the Lord," which seems to be common to all, he has described the chief mark of reverence for God. As, however, fear itself is the beginning of wisdom and the source of blessedness—for they that fear the Lord are blessed—he has plainly marked himself out as the teacher for instruction in wisdom and the guide to the attainment of blessedness.”

“..."The fear of the Lord," therefore, "is the beginning of wisdom." "Understanding is good" [Psalm 111:10]. Who gainsayeth? But to understand, and not to do, is dangerous. It is "good," therefore, "to those that do there after." Nor let it lift up the mind unto pride; for, "the praise of Him," the fear of whom is the beginning of wisdom, "endureth for ever:" and this will be the reward, this the end, this the everlasting station and abode. There are found the true commandments, made fast for ever and ever; here is the very heritage of the New Covenant commanded for ever. "One thing," he saith, "I have desired of the Lord, which I will require: even that I may dwell in the house of the Lord all the days of my life." For, "blessed are they that dwell in the house" of the Lord: "they will be alway praising" Him; for "His praise endureth for ever."”

“No one accomplishes these ten commandments by their own strength, unless assisted by the grace of God. If therefore no one fulfills the law by their own strength, unless God aids with His Spirit; now recall how the Holy Spirit is commended in the sevenfold number, just as the holy prophet says, that the man be filled with the Spirit of God, of wisdom and understanding, of counsel and fortitude, of knowledge and piety, the Spirit of the fear of God. These seven operations commend the Holy Spirit in the sevenfold number, who, as if descending to us, begins with wisdom and ends with fear. But we, ascending, begin with fear and are perfected in wisdom. For the fear of the Lord is the beginning of wisdom.”

“And again he said, "The fear of the Lord is the beginning of wisdom." Now the end of the path of good works is spiritual love, therefore from love divine wisdom is produced, and the blessed David well taught us that the beginning of this way of wisdom is the fear of God. For as to every matter in [this] world there is a beginning and an end, and as the paths which are trodden down naturally by the passage of footsteps have also a beginning and an end, even so hath the path of virtue a beginning and an end; its beginning is the fear of God, and its end is the wisdom which is born of love. And it is right that every man who wisheth to begin the Christian life should begin it with the fear of God, even according to the teaching of the blessed David.”

“No one is saved without knowledge of himself, from which indeed the mother of salvation, humility, arises, and the fear of the Lord, which itself, just as it is the beginning of wisdom, so also is the beginning of salvation. No one, I say, is saved without that knowledge, who yet has the age and faculty of knowing. This I say on account of little children and the mentally deficient, whose case is different. What if you are ignorant of God? Can there be hope of salvation with ignorance of God? Not even this. For you can neither love one whom you do not know, nor possess one whom you have not loved. Know yourself therefore, that you may fear God; know him, that you may likewise appease him. In the one you are initiated into wisdom, in the other you are also brought to perfection, because the beginning of wisdom is the fear of the Lord, and the fullness of the law is love. Both ignorances therefore must be guarded against by you, just as without the fear and love of God salvation cannot exist. The rest are indifferent, having neither salvation if they are known, nor damnation if they are not known.”

“The fear of God avails for obtaining the illumination of divine wisdom, because "the fear of the Lord is the beginning of wisdom." For the fear of the Lord is the extrinsic principle of wisdom and the intrinsic principle and the complement of wisdom; because there is servile fear, and this is the initiator of wisdom, because, just as the needle introduces the thread and does not remain with the thread, so servile fear introduces wisdom and does not remain with wisdom. Another is the fear of punishment and of offending God; and this is the intrinsic beginning of wisdom and the root of wisdom. The third is the fear of filial reverence: and this is the complement of wisdom, because "the fullness of wisdom is to fear God." Fear produces these three things in us, because "the fear of the Lord is the beginning of wisdom," and "the root of wisdom is to fear God," and "the fullness of wisdom is to fear God": Job: "Behold, the fear of the Lord, that itself is wisdom." He who does not fear God knows nothing.”

“"Holy and terrible is his name; the fear of the Lord is the beginning of wisdom; a good understanding have all who practice it." Prudential understanding teaches what is to be avoided, namely every evil. For every person who wishes to be directed toward the good must fear God, so as to avoid every evil. Therefore prudential understanding teaches first what is to be avoided, namely every evil.”
